Notes
ことから, though のだから and ものだから both take な there. A な-adjective does
keep its な (便利なことから).
What follows is a finding, never a wish or a request: not ×安いことから、
買ってください — 安いから、買ってください.

から gives the speaker's own reason and freely fronts a command or an opinion; ことから names an observable fact as the GROUND a finding or a name rests on, so its main clause is a conclusion stated as public record (〜と考えられている, 〜と呼ばれる) and never a bare command at the hearer.
ところを見ると needs the evidence witnessed on the spot and must end in a conjecture; ことから takes evidence of any age, the record and the archive included, and its main clause can land flat — a name that stuck (〜と呼ばれる), a finding on the record (〜と考えられている) — which is why reports and encyclopaedia entries take ことから and never ところを見ると.
に基づいて takes a NOUN — a rule, a standard or a finding — and the main clause is carried out in conformity with it (規定に基づいて処分する); ことから takes a whole CLAUSE and the main clause is what was inferred from it, so a clause reaches に基づいて only by way of 〜ことに基づいて.
Lookalikes
One だ apart, and they reason in opposite directions — ことだから reads a known person's character and ventures a guess about them (彼のことだから、また遅れるだろう), while ことから starts from an observed fact and lands on a conclusion anyone could check.
